  1. 1. On platelet-rich plasma in reconstructive dental implant surgery

    Författare :Andreas Thor; Göteborgs universitet; []
    Nyckelord :autogenous bone graft; bone formation; coagulation; clinical study; complement; dental implant; experimental study; growth factors; platelet activation; platelet-rich plasma; sinus lift surgery; thrombogenicity;

    Sammanfattning : Abstract Background Severe athrophy of the edentulous maxilla may require augmentation before implants can be placed. Autogenous bone has been used for reconstruction in block or in particulated form. LÄS MER

  3. 2. Adenosine action on platelets : pharmacological and functional studies in human platelets in vitro

    Författare :Ulla Söderbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :adenosine; adenosine analogs; methylxanthines; cyclic AMP; ADP; dipyridamole; platelet-rich plasma; whole blood aggregatron; human. Ulla SöderbäckAdenosine action on platelets. Pharmacological and functional studies in human pl;

    Sammanfattning : The endogenous purine adenosine (ADO) is known to inhibit platelet aggregation in vitro through increased platelet levels of cyclic AMP. This effect is ADO-A2-receptor-mediated through stimulation of membrane adenylyl cyclase. LÄS MER

  4. 3. The fibrinolytic enzyme system : new markers of potential interest in cardiovascular disease

    Författare :Arvid Nordenhem; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Fibrinolysis; myocardial infarction; tissue plasminogen activator; PAI-1;

    Sammanfattning : Impaired fibrinolytic function, mainly due to elevated plasma levels of PAI-1, is a common finding in patients with coronary heart disease. Determination or evaluation of the plasma PAI-1 concentrations are complicated, due to a natural variation in blood plasma or due to other reasons, such as a poor stability under physiological conditions.

  5. 4. Investigation of Incompatibility Reactions Caused by Biomaterials in Contact with Whole Blood Using a New in vitro Model

    Författare :Jaan Hong; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; biomaterials; coagulation; complement; heparin; leukocytes; platelets; PVC; titanium; Onkologi; Oncology; Onkologi; Clinical Immunology; klinisk immunologi;

    Sammanfattning : This thesis describes a new in vitro slide chamber model that makes it possible to conduct studies of molecular and cellular interactions between whole blood and biomaterials. The model proved to be a suitable tool for detection of cell and platelet binding to a biomaterial surface. LÄS MER

  7. 5. Effects of pH on platelets release of growth factors in wound healing

    Författare :Yawei Liu; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Wound healing is thought to involve a complex series of interactions between biochemical mediators, cells and extracellular matrix. Known to stimulate cellular movement, proliferation and biosynthetic activity, growth factors may play a significant role in stimulating wound repair. This thesis focuses on the early phase of wound healing. LÄS MER
